• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu san) OR (vu ban)) ky ((nang xa) OR (nang x)) hoi. thien he am thuc dong thanh ve cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu san) OR (vu ban)) ky ((nang xa) or (nang x)) hoi. thien he am thuc dong thanh ve cua te*".
